CROWN CAPPED CONTAINER Filed April 26, 1943 Patented Dec. 1 s, 1945'UNITED STATES PATENT OFFICE caowN oarrnn comma William F. Punte,Passaic, N. .L, assignor to Continental Can Company, Inc., New York, N.Y., a corporation of New York Application April 26, 1943, Serial No.484,631 4 Claims. .01. 220-60) The invention relates generally to theart of manufacturing metallic receptacles and prima-' rily seeks toprovide a container structure peculiarly adaptable for being efficientlysealed by a closure of the crown cap type.

It is well known that considerable difficulty has been experienced inthe past in attempting to provide eflicient sealing closures of thereadily removable crimped skirt or crown cap type in containers in whichthe opening to be sealed is Figure 2 is a vertical cross sectional view,the section being taken on the line 2-2 on Figure -1. Figure 3 is anenlarged fragmentary. sectional view showing the cover orclos'ure memberapvery large, and this is particularly true in the tremity or mouthdefining edge of the body is bent and rebent to provide a flatwise,outwardly and horizontally directed multi-thickness stiffener beadpresenting an upper flat and relatively wide sealing gasket engagingsurface and a clamp shoulder under which the crimped skirt of thecomplementary closure can engage, said closure having formed thereon achannel in which to receive said bead and having therein a sealinggasket for engaging in sealing contact on the flat upper surface of thebead and a crimped skirt. edge portion adapted to be deformed afterplacement of the closure on the container body to engage under saidshoulder and removably secure the attachment of the closure on thecontainer body.

Another object of the invention is to provide a v container of thecharacter stated in which the body and closure are rectangular in shape,and in which the crimps in the skirt of the closure are arranged insymmetrically spaced groups.

plied to the body but not secured thereon.

Figure 415 a view similar to Figure 3 illustrating the cover securelyclamped in position on the container body.

In the example of embodiment of the invention herein illustrated thecontainer is shown as rectangular in shape and of the relatively shallowtype employed in the packaging of sardines or the like. It is to beunderstood, however, that the invention is not limited in scope toembodiment in rectangular or oblong containers alone, or tocontainerswhich are relatively shallow. The invention comprehendsembodiment thereof in any form of container having a large mouth andflexible walls defining that .mouth and which must be provided with astiffened upper edge extremity of thenature herein disclosed in order toadapt the same for receiving readily removable closures of the crown capor crimped skirt The herein disclosed container includes a base or'bottom 5 and side-and end walls designated 6 and 1, respectively, andcooperating with the bottom 5 in providing a relatively shallow oblongor rectangular container body.

At its upper extremity defining the open mouth, the container body isequipped with a multiple thickness, horizontally flattened stiffenerbead 8 which stiflens the upper extremity of the body so as to enablesecure sealing of the container with a readily removable closure of thecrown cap or crimped skirt type. The bead may be formed by outwardlyheading the body walls 6 With the above and other objects in view thatwill hereinafter appear. the nature of the invention will be more fullyunderstood by following the detailed description, the appended claimsand the several views illustrated in the accompanying drawing.

In the drawing: Figure 1 is a plan view illustrating the invention.

and 1 adjacent the upper end thereof and outwardly flanging the upperedge extremity and then'flattening the bead and flange to form the flat,sort of pleated stiffening rib or bead clearly illustrated in Figures 3and 4 and which has the raw metal edge portion thereof disposeduppermost and directed outwardly.

The container body is adapted to be securely sealed by a closureincluding a relatively flat body portion 9 and an annular channel 10shaped to receive and embrace the upper extremity of the can body andespecially the stiffener head 8 thereof. The channel I0 is equipped witha sealing gasket ll adapted to engage and eiiiciently seal against theuppermost fiat surface. of the stiffener bead or rib 8 in the mannerclearly illustrated in Figures 3 and 4. It will be observed by referenceto Figures 3 an 4 that the channel I B is defined in part by an ashoulder I 2 adapted to be forced under the bead or rib 8 for securely,but removably clamping the closure on the body in the mannerclearlyillustrated in Figure 4. In order to provide just the properamount of resiliency ofthe skirt beneath the shoulder l2, said skirt isprovided with symmetrically spaced groups of crimps l3,

By reason of the provision of the multiple thickness, horizontallydisposed stiffener bead or rib l the upper extremity of the containerbody is made sufficiently rigid to enable the provision of an emcientseal by employment of the crown cap or crimped skirt type of closuremember illustrated in the drawing, and it will be obvious that itisadvantageous to provide a container of the character described with aclosure member that can be readily pried off without the necessity ofusing a can opener, and which may conveniently be replaced toreestablish the closure of the container after th initial removal of theclosure member.

. It is of course to be understood that the details of structure and thearrangement of parts may be variously changed and modified withoutdeparting from the spirit and scope of the invention.

I claim:

1. A container of the character described comprising a rectangular bodywith rounded corners and having a bottom, wall extending uprightlysmoothly and without interruption from the bottom to the upper extremitythereof and defining a large filler opening at said upper extremity,said upper extremity terminating in a horizontally flattened outwardlydirected stiffener bead of uni-.

form thickness throughout the circumference thereof and formed by threethicknesses of the body extremity stock folded flat upon each otherpleat fashion with a raw edge portion thereof disasensee smoothly andvwithout interruption from the bottom to the upper extremity thereof anddefining a large filler opening at said upper extremity. said upperextremity terminating in a horizontally flattened outwardly directedstiffener bead of uniform thickness throughout the circumference thereofand formed by three thicknesses of the body extremity stock folded flatupon each other pleat fashion with a raw edge portion thereof disposeduppermost and directly outwardly, and a rectangular closure with roundedcorners and ineluding a deep bead embracing channel for embracing andsupporting said head against inward bending and having a sealing gaskettherein for posed uppermost and directed outwardly, and a rectangularclosure with rounded corners and including a deep bead embracing channelfor embracing and supporting said bead against inward bending and havinga sealing gasket therein for engaging in sealing contact with saidlbead,said channel being defined in part by an outer skirt extending below thebead and having a shoulder placed at such depth on said skirt as to beadapted to be forced under said flattened bead for securely .butremovably clamping the closure on the body.

2. A container of the character described com engaging in sealingcontact with said bead, said channel being defined in part by an outerskirt extending below the bead and having a shoulder placed at suchdepth on said skirt as to be adapted to be forced under said flattenedbead for securely but removably clamping the closure on the body, saidskirt being provided with symmetrically spaced groups of preformedcrimps extending beneath said shoulder.

3. A container body comprising a bottom and side and end wallsdimensioned to give to the body a rectangular shape with roundedcorners. the upper edge terminus of said walls being folded upon itselfpleat fashion to form a triple thickness horizontal stiffener bead withthe raw edge disposed uppermost and directed outwardly.
